AI Technical Summary

⚠Technical Problem

In inter-cell multiple TRP operations in 3GPP Release 17, existing technologies struggle to effectively handle PDSCH rate matching and channel coding between different cells, especially when the synchronization signal block modes of different cells are different, resulting in low signal transmission efficiency.

⚗Method used

By mapping different CORESET pool indices to different serving cell identifiers on the base station side, and combining TCI status and QCL relationship, rate matching and channel coding of PDSCH are achieved, ensuring that PDSCH transmission between different cells can be independently scheduled and rate matched.

🎯Benefits of technology

It improves the signal transmission efficiency and flexibility of inter-cell multi-TRP operations, enhances the rate matching capability of PDSCH, adapts to the differences in synchronization signal block modes between different cells, and improves the performance of the communication system.

Abstract

The present application relates to a method and apparatus for communication. The method comprises: mapping a first CORESET pool index associated with a first CORESET pool to a first serving cell ID associated with a first serving cell; mapping a second CORESET pool index associated with a second CORESET pool to a second serving cell ID associated with a second serving cell; generating a first physical downlink control channel (PDCCH) transmission for transmission to a user equipment (UE) using resource elements from a first CORESET of the first CORESET pool to schedule a first transmission in the first serving cell or the second serving cell, the first transmission to include a PDSCH transmission, a PUSCH transmission, a PUCCH transmission, or an aperiodic CSI-RS; associating a CORESET from the first CORESET pool with a TCI state from a first set of TCI states activated for the first serving cell; and associating a CORESET from the second CORESET pool with a TCI state from a second set of TCI states activated for the second serving cell.
